In the last of the "children" recruitment chapters (though not the most diffifult), you will face an eery, morphing level with multiple powerful enemies. As you make your way through the map, the walls will begin to crumble and reform turn by turn, until eventually all walls will remain crumbled.

In this map you'll start off on the right side of the map towards the middle. Nah will be a non-playable character who seems to be in a room you can't get to at the moment. For this map, sword users are the best because many of the enemies are axe wielding.

Act first by quickly getting near the room Nah is trapped in, as the wall will open up after the second turn, making her vulnerable to enemy attack. Use Chrom or Nowi to go over to her and talk to her.

After recruiting Nah use your party to go to the chest on the bottom left of the map and finish off any enemies along the way. Use a key or a unit with locksmith to open the chest. After that the objective is to get to the top of the map and finish off the remaining enemy units. Tip: Keep your party together the walls are contantly breaking down and repairing themselves closing and opening up paths. It is really easy to get a unit off to themselves if you let it stray to far away.

If you let your sword users do most of the fighting and keep your party together you can keep your units alive and sustain miminal damage. Just slowly work your way up with your party till you get to the boss. Then take him out and finish the map.

After recruiting Nah, proceed carefully through the map, making sure your units do not get isolated by an open wall that closes on the next turn. Also, be wary of enemies with long-range magic attacks.

The two safest options to complete this level are to either a) wait until the walls come down and stay down, which starts to happen at turn 30, or b) simply open the door on the left to safely allow all your units to pass through.
